Another purpose is to produce a container capable of withstanding rough handling.

1 without yieldingof its walls or causing leaks,

'20 and which is readily opened when the contents is required.

These important purposes are attained by the novel, practical and simple construction and combination of parts hereinafter described and shown in the annexed drawing, constituting a component of this disclosure, and in which p Figure 1 is a perspective view of the container blankas partially coiled. f

Figure 7 is an enlarged longitudinal sectionalrviewcof the upper part of the finished container, the view being taken onllne 'Z7 of Figure 6. r

The upright walls of the container are made from a unitary oblong. rectangular 45. blank 10 of heavily calendered paper flat, un-

creased and presenting four straight unbroken edges.

The width of the blank is as to pro-' duce a complete container, entirely without 5.0 waste, and its length is preferably such as to receiving seat 15 having a. raised marginal The raised flange 16 is ta ered 1931. Serial no. 520,283.

be plurally coiled to constitute a cylinder 11, the end edges passing each other and being firmly and smoothly secured, both inside and outside, by an adhesive unaffected by liquids.

.These cylinders, which are uniform in diameter, length and all other respects, are placed upon a mandrel, tapered for approximately half the length of the container, and there subjected to a rotating conical die which, in connection with the mandrel, produce a series of evenly spaced, uniform plaits or ruflles 12 widest at their upper extremity and gradually merging, as at 13 into the cylindrical body 14, these plaits being all turned in the same direction and produce an essentially smooth surface.

' The mouth portion, that is the upper end, of the container is enlarged b specially designed machinery, which also orms a flat cap flange 16 tapered slightly outward above an annular recess, which is formed by an extension or head 17, level with the seat 15, and which is adapted to receive a plain fiat circular cap 18 and retain it therein. The bottle is conveniently manipulable by this bead and is rigidified thereat by the cap 18.

outwardly to permit easy insertion o the cap, after which the flange is folded inwardly by plaiting, covering the cap and producing an effective double seal on the container, as at 19 in Figs. ,5 and 6. Said seal, which is substantially dome-shaped, serves to cast off any particles or moisture which would otherwise rest or accumulate on the seat 18.

The bottom of the container is preferably formed by the insertion of a flanged disc, treated with an insoluble adhesive and further secured by forming an annular row of corrugations 20, thereafter coiling the extending-lower edges' of the bottom flange to produce an inset bead, as indicated at 21 in Fig. 5.

' 1 Both the inside and outside of the container are coated with melted mineral wax, thus efl'ectually sealing the contents against the passage of air or liquids. I

Due to the double or triple walls of the container ,an efiicient, firm and conveniently handled structure is produced, and b reason of designing s ecial machiner or its construction, in a dition to its simplicity and freedom of waste, the containers can be produced at a low cost.

From the foregoing it will be seen that a simple device for this purpose has been disclosed in the preferred form of its embodiment, but it is not desired to restrict the dc tails to the exact construction shown, it being obvious that changes, not involving the exercise of invention, may be made without conflicting with the scope of the appended claims.

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent is 1. A paper container comprising a smooth cylindrical body having a plaited tapering v upper portion, an annular flange extending outwardly near the top to constitute a cap receiving seat, and plaited elements on said flange to completely cover a cap positioned on said seat.

2. A paper container comprising a plain cylindrical body having a tapering upper portion flanged outwardly near the top to form a flat cap receiving seat, said tapering portion being plaited and a cylindrical extension thereabove also plaited and infolded to extend over a cap on said seat.

3. A paper container for liquids having a.

5. A paper container comprising a cylin-' drical body having a tapering upper portion flanged outwardly near the top to, form a flat cap receiving seat, a series of overlying plaits formed in a cylindrical extension on the margin of said seat, said plaits being bent inwardly to closely and completely cover a cap on the seat, said plaits being tightly LMMQQQ I. A' bottle comprising in combination with a sheet of paper which is formed into a body having acylindrical portion, and a neck tapering from one end thereof and forming at its narrow end a mouth, a bottom for the other end of said portion, a circumferential.-

extended bead at said mouth, said head providing'an internal seat, a flatcap supported on said seat, and a portion of said sheet continuous with said bead and turned inwardly and downwardly on to said cap to shield the latter.

8. A bottle comprising 'in combination with a sheet of paper which is formed into a. body having a cylindrical portion, and a neck tapering from one end of said portion and forming at its narrow end a mouth, a bottom for the other end of said portion, a circumferential extended bead at said mouth, saidbead providing an internal seat, a flat cap supported on said seat, a portion of said sheet continuous with said bead and turned inwardly and downwardly on to said cap to shield the .latter, said head providing manipulating means for the bottle, and means for rigidifying said mouth comprising said cap during the manipulating operation.
